    USER WARNINGS RECOMMENDATIONS FOR THE PROPER USE OF WEIGHING INSTRUMENT Keep away from heat sources and direct sunlight Repair the instrument from rain (except special IP versions) Do not wash with water jets (except special IP versions) Do not dip in water Do not spill liquid on the instrument Do not use solvents to clean the instrument Do not install in areas subject to explosion hazard (except special Atex versions)
  • Page 6 WELDING: Avoid welding with the load cells already installed. If this cannot be avoided, place the welder ground clamp close to the required welding point to prevent sending current through the load cell body. WINDY CONDITIONS - KNOCKS - VIBRATIONS: The use of weigh modules is strongly recommended for all load cells to compensate for misalignment of the support surfaces.
